HONG KONG, Oct 22 — Hong Kong stocks tumbled more than three per cent Thursday as tech firms joined an Asia-wide selloff fuelled by growing worries about the AI investment boom.

The Hang Seng Index dived 3.1 per cent to 22,923.18 in afternoon trade, with Chinese ecommerce giant Alibaba shedding more than six per cent, rival JD.com off more than four per cent and NetEase off nearly seven per cent. — AFP
